BUCKEYE ASSIGNOR TO THE CAR TRUCK.

Application filed December 16, 1925.

This invention relates to car trucks and has special reference to thebolster, spring plank, and brake hanger brackets, the primary objectbeing to provide a novel arrangement and construction of these partswhich will permit wheel changes to be made without requiring a completedisassembling of the truck. The invention is illustrated in theaccompanying drawings and consists in certain novel features which willbe hereinafter first-fully described and then more particularly definedin the claims.

In the drawings, Figure 1 is a plan view of a portion of a truck showingthe invention; Figure 2 is a side view, partly in section; Figure 3 is aview showing the bolster and spring plank in elevation and the sideframe in transverse vertical section;

Figure 4 is an end elevation of the spring plank showing the brakehanger brackets;

Figure 5 is a plan view of the parts shown in Figure 4.

The side frame 1 is of the usual general form, carrying journal boxes 2-'Wh1Cl1 are preferably integral with the frame. The

side frame is constructed with an opening 3 therethrough to receive theends of the bolster 4 and spring plank 5, the latter carrying the brakehanger brackets 6. The bolster is of the usual general form and isprovided on its sides with vertically extending stop lugs, shoulders orprojections 7, the sides of the bolster between the stops 7 and the endsbeing plane or free of projections. The

spring plank is substantially U-shaped in cross section, as shown inFigures 2 and 4,

and is constructed from pressed steel or other sheet material having thenecessary strength and durability. The brake-hanger brackets areprovided by a U-shaped casting which is slid over the end of the springplank and is preferably constructed with ledges or ribs 8 to rest on theupper surfaces of the side flanges of the plank, or if desired it may beconstructed to rest on the web of the spring plank. The spring plank islocked in the side frame by interengaging bosses and sockets, as shownat 9.

The stops 7 on the bolster abut the inner sides of the brake hangerbrackets approximately at the center thereof, and on the outer sides ofthe brackets, above their centers, are outwardl projecting stops 10which abut the inner si e of the side frame, while the bottom of thecasting at its outer edge Serial No. 75,865.

abuts the bottom web of the side frame, as shown at 11. It will be seenthat by this arrangement of the stops, the lateral forces exertedthrough the bolster will be distributed and applied to the side frame atlower levels than heretofore so thatrocking of the side frame isminimized.

In Figure 3, I have indicated, at 12, an extension bracket which may besecured to the brake hanger bracket and furnish a support for brake beamcarriers which are often employed in modern construction.

With the parts arranged as shown and described, when wheel changes areto be made, the spring plank is jacked up until the lugs and sockets at9 are out of engagement whereupon the side frame may be withdrawnlaterally, the springs, spring plank, bolster", and brake partsremaining intact. The stops 7 and 10, besides distributing the lateralforces, serve as guides for the side frame in its verticalmovement'relative to the bolster and the spring plank.

Having fully described my invention what I claim as new and desire tosecure by Let- 'ters Patent, is

1. In a car truck, a side frame, a spring lank locked in the side frame,a bolster liaving its end inserted in the side frame above the springplank, a brake hanger support carried by the spring plank, a guide stopon the bolster abutting the inner side of the brake hanger support, anda guide stop on the outer side of said support abutting the side frame.7

In a car truck, a side frame, plank locked in the side frame, abrake hanger support carried by the spring plank with bottom portionbelow the spring plank abutting the side frame, a bolster having its endinserted in the side frame above the spring plank, a stop on the outerside of the brake hanger support abutting the side frame, and a stop onthe bolster abutting the inner side of said support.-

3. In a car truck, a spring plank having upstanding side flanges, and aU-shaped brake hanger support engaged about the spring plank and havingshoulders on the 1nner surfaces of its side members resting on theflanges of the spring plank.
